Abstract

The utility model discloses a roller shape measuring stand which is characterized in that the measuring stand is composed of a guide bar and a V-shaped supporting seat which is provided with a magnetism meter seat, so that the measuring stand can be firmly adsorbed on a roller surface. The guide bar is as long as the working surface of a measured roller. A measuring head frame sliding on the guide rod inputs test signals to a micro computer for processing through an inductive measuring head; results can be printed and drawn out. The utility model has the advantages of convenient operation, and precise and reliable measured results.

Description

Roller shape measuring stand

The utility model relates to a kind of measurement bay of measuring roll profile with mechanical means.

In steel rolling was produced, the roll shape of roll directly influenced the template quality of band steel, thus need in time to understand the roll shape situation of change of roll after use, to determine the grinding process of roll.At present, all adopt the vary in diameter on the survey instruments measurement roll axis directions such as milscale or saddle frame aborning, the roller curve of the roll that draws again.If the speed of Ce Lianging is very slow like this, and will measure bottom roll the time, topping roll must be pulled down from the roller frame, operates very inconvenient.

The purpose of this utility model is exactly that a kind of measurement mechanism easy to use will be provided.

To achieve these goals, proposed a kind of roll profile measurement bay, it is characterized in that measurement bay is made up of guide pole and V-type bearing, the workplace of guide pole and tested roll is isometric, measure the headstock and on guide pole, slide, can measure along the vary in diameter on the roll axis direction then.

Because measurement bay of the present utility model adopts Magnetic gauge stand to be fixed on the roll, so measurement bay can be placed on horizontal level, also can be placed on upright position or arbitrarily angled placement, use and convenience.Use the micro computer deal with data, measurement result is accurately reliable.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Fig. 1 is the front elevation of the utility model measurement bay;

Fig. 2 is the vertical view of the utility model measurement bay;

Fig. 3 is the side view of the utility model measurement bay.

As can be seen from the figure, the utility model measurement bay is made up of guide pole 1, V-type bearing 2, and the back-up block 4 and the magnetic force gauge stand 3 of wedge shape arranged on the V-type bearing, measures the headstock 5 and can move on guide pole.During measurement, at first measurement bay is placed on the roll,, then measurement bay can be leaned against on the roll, back-up block is well contacted with roll surface,, do not produce distortion, reduce measuring error even guide pole is parallel with roll axis if bottom roll does not take off from roller base.Rotation magnetic force gauge stand handle makes the gauge stand bottom have magnetic then, and whole like this measurement bay just is adsorbed on roller surface securely.When using the utility model measurement bay, want personal computer system of supporting use, personal computer is PC-1500, the data acquisition of computer inductance type measuring head, measuring head are contained in to be measured on the headstock, when measuring the headstock when guide pole moves, can be with each test point data-signal input computer, with the reference data comparison process of original storage in the computer, just can get the vary in diameter value of each test point, roller curve also can draw.In order to reduce measuring error, obtaining of reference data is crucial, for this reason, select the new roller of a precision machining, data with the measurement bay collection are input to micro computer, because data have comprised the systematic error of measurement bay itself, so must use same measurement bay at other roll of measurement.The rigidity of measurement bay guide pole also is the key factor that influences measuring error, and it is that the above aluminium section bar of 2.5mm is made that the utility model is measured the guide pole wall thickness, tests to show that measuring error that such guide pole causes is in the 10-20 micron.

Claims

1, a kind of roll profile measurement bay is characterized in that measurement bay is made up of guide pole and V-type bearing, and the workplace of guide pole and tested roll is isometric, measures the headstock and can slide on guide pole.

2, measurement bay as claimed in claim 1 is characterized in that being equipped with on the V-type bearing magnetic force gauge stand.
